cannot be resolved or is not a field 等待高手解决，谢谢
res/xml下面已经定义了test.xml

XML code

<?xml version="1.0" encoding="utf-8"?>  <PreferenceScreen   xmlns:android="http://schemas.android.com/apk/res/android">             <PreferenceScreen             android:key="test"             android:title="tddddddddd"            >             </PreferenceScreen>     </PreferenceScreen> 

//下面代码报错

Java code

protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);         addPreferencesFromResource(R.xml.test);         }

R.java

Java code

public static final class xml {        public static final int test=0x7f050000;        ......}

//错误信息
test cannot be resolved or is not a field

[解决办法]
addPreferencesFromResource(R.xml.test); ？？？
[解决办法]
代码没看出问题...
